Mesogenic Properties of 2', 3''''-dimethyl-p-sexiphenyl
Abstract
The mesogenic properties of 2',3''''-dimethyl-p-sexiphenyl, 2, have been investigated. Although three endothermic transitions were observed only two were reproducible and correspond to a crystal to crystal change and a crystal to nematic change. A larger than expected decrease in the on-set temperature for the nematic transition and the absence of a smectic transition in 2 compared to p-sexiphenyl, 1, have been observed. These data support a proposed 'lock-key' model for the molecular conformation of the parent compound, 1 which is not present in 2.
